Liquid crystal display device

Abstract

A liquid crystal display device includes: a first substrate; a second substrate; and a liquid crystal layer that contains liquid crystal molecules. The first substrate includes, in the following order toward the liquid crystal layer, a bus line extending in a first direction, a first electrode, an insulating layer, and a second electrode. The second electrode is provided with a longitudinal portion extending in a second direction in a pixel region. The initial alignment direction of the liquid crystal molecules and the second direction satisfy the following relation (A) or (B): (A) the initial alignment direction of the liquid crystal molecules is at an angle of 0° to +5° and the second direction is at a negative angle; and (B) the initial alignment direction of the liquid crystal molecules is at an angle of −5° to 0° and the second direction is at a positive angle.

What is claimed is: 
     
         1 . A liquid crystal display device comprising:
 a first substrate;   a second substrate facing the first substrate; and   a liquid crystal layer that is sandwiched between the first substrate and the second substrate and contains liquid crystal molecules,   the first substrate including, in the following order toward the liquid crystal layer, a bus line extending in a first direction, a first electrode, an insulating layer, and a second electrode,   the second electrode being provided with a longitudinal portion extending in a second direction in a pixel region,   an initial alignment direction of the liquid crystal molecules and the second direction satisfying the following relation (A) or (B) when an angle is defined to be positive in a clockwise direction with the first direction taken as a reference:   (A) the initial alignment direction of the liquid crystal molecules is at an angle of 0° to +5° and the second direction is at a negative angle; and   (B) the initial alignment direction of the liquid crystal molecules is at an angle of −5° to 0° and the second direction is at a positive angle.

 wherein the longitudinal portion is part of an electrode portion of the second electrode.   
     
     
         3 . The liquid crystal display device according to  claim 1 ,
 wherein the longitudinal portion is part of an aperture formed in the second electrode.   
     
     
         4 . The liquid crystal display device according to  claim 1 ,
 wherein the first direction and the second direction form an angle of greater than 0° and 10° or smaller.   
     
     
         5 . The liquid crystal display device according to  claim 1 ,
 wherein the initial alignment direction of the liquid crystal molecules and the second direction form an angle of 10° to 15°.
